Definitions

  • the invention relates to an end termination for a superconducting cable according to the preamble of claim 1.
  • Superconducting cables require at their ends means by which current and voltage are transferred from the low temperature of the cable to ambient temperature.
  • the invention has for its object to find a solution that allows, while maintaining the electrical contact, a movement of the conductor of the superconducting cable or a normal conductor connected to the end of the superconducting cable.
  • the main advantage of the invention is the fact that can be dispensed with elaborate evasive solutions to remedy the problem, and on a product available on the market, namely the tubular component, can be used.
  • Another advantage of the invention lies in the fact that the tubular member always guarantees a contact, even with a radial expansion or contraction due to its resilient blades.
  • FIG. 1 shows a lateral section through an arrangement for connecting a superconducting cable 1 to an end termination 2.
  • the superconducting cable 1 consists, as is known per se, of a cable core and a cryostat surrounding the cable core.
  • the cable core consists of a conductor and a dielectric surrounding the conductor.
  • a superconducting cable is from the WO 02/15203 known.
  • the end termination 2 consists of a current conductor 2a, an insulator 2b surrounding the current conductor 2a and a field control element 2c.
  • the interior 2d of the insulator 2b is advantageously filled with insulating oil.
  • the pipe socket 4 is double-shelled, wherein the space between the two shells 4a and 4b is filled with a super insulation and evacuated.
  • the space located between the conductor 2a and the inner shell 4a is filled with an insulating material, preferably a foam.
  • a tubular member 7 is electrically connected, in the opening of the bolt or the tube 6 can slide longitudinally displaceable.
  • the tubular member 7 has a plurality of radially inwardly and / or outwardly resilient blades.
  • FIG. 2 shows a section through the region of the tubular component 7, wherein the tubular component 7 is shown only partially cut away.
  • the tubular member 7 is electrically connected to a transition piece 8, which in turn is electrically connected to the conductor 2a.
  • the tubular member 7 may have both inwardly projecting slats 7a and outwardly projecting slats 7b, the radially inwardly (slats 7a) resiliently supported on the tube or bolt 6 and radially outward (slats 7b) resiliently in the bore of the Support transition piece 8.
  • the lamellae 7a and 7b provide a permanent contact between the tube or bolt 6 and the transition piece 8 even during a displacement of the tube or bolt 6 in the longitudinal direction of the cable 1.
  • the lamellae 7a and 7b also take on a radial dilation and contraction, when the cable is taken out of service, ie the cooling of the cable is switched off or switched on.
  • the tubular member 7 is advantageously made of copper and has on its surface a thin layer of silver.
  • FIG. 3 shows a lateral section in the region of the tubular component.
  • the tubular component 7 is fixed in the transition piece 8.
  • the tubular member 7 only inwardly projecting lamellae 7a, which ensure electrical contact between the bolt or the tube 6 and the tubular member 7 and thus an electrically conductive connection to the transition piece 8 and the conductor 2a and indeed during the heating or cooling phase of the cable 1, in which the tube or the bolt 6 slides in the tubular member 7.
